Library Themed Cards

I've been a high school librarian for over a decade now, and I’ve got a display of library and story themed Magic cards. I’ve got three cards of each color and three colorless.

Here's my current lineup:

• White: Giant Killer, Haunted Library, History of Benalia
• Blue: Animate Library, Browse, Hard Cover
• Black: Phyrexian Librarian, Poet’s Quill, Shrouded Lore
• Red: Book Devourer, Enthusiastic Study, Orcish Librarian
• Green: Curious Pair, Magus of the Library, Mild-Mannered Librarian
• Colorless: Cogwork Librarian, The Biblioplex, Island (Jumpstart: Books)

I feel like it's time for an update, especially in white, black, and red. I haven't been keeping up with the last few years of releases, which is why I'm soliciting reccomendations.

• White: I chose Giant Killer and History of Benalia for their storybook frame and saga typing, but I'm not sold on them. 
• Black: Phyrexian Librarian is a keeper, but the other two could definitely be replaced. Black doesn't seem to have a lot of options in the theme though.
• Red: Orcish Librarian is perfect. I'm considering adding Crime Novelist in place of Enthuiastic Study.
• Green: Curious Pair was chosen for the storybook frame. Could be replaced.
• Blue and Colorless: I'm pretty happy with these, but I'm open to thoughts.

Also, I’m considering a second display. Perhaps the first nine could be Legendary books and/or librarians and/or story tellers. I feel like Birgi, Huatli, and Tamiyo are obvious choices. The second nine could be all blue cards. There are lots of blue cards that fit the theme (Bury in Books, Into the Story, Novellamental). 

What cards would you recommend for a library/story-themed display?
